water lettuce is a warm water-loving plant that floats on the surface. It creates wet lettuce-like clusters from light green sheets, that feel almost velvet because of little hairs on the surface. The sheets form medium leaves thick and soft, usually around six inches long.
They stay dry, during long roots swing freely below in the water. Those swinging roots are blessed food for many fish in aquariums.
What Is Water Lettuce and How to Care for It
The scientific name of the plant is Pistia stratiotes. It belongs to the family Araceae and is the only species in the tribe Pistieae. One knows it under several names, as water cabbage, Nile cabbage and shell flower.
It happens in many parts of the southern United States and one considers it a harmful weed here.
water lettuce is a fast growing floating plant. It breeds soon and can create thick coverings, that block rivers. It most likes to live in slowly moving water, as in pools, lakes, flooded areas, irrigation channels and decorative ponds.
In mild regions it sometimes manages to return after winter through seeds, if the soil and water supply answer. During very long dryness water lettuce in pools covers teh water and stops drying by means of shade, but when the dryness dried the pool, the lettuce died away outside.
In aquariums water lettuce right away does the tank feel more natural. The long roots give shade and help to absorb extra nitrates. It also takes phosphates and adds oxygen to the water.
Truly it helps to keep nitrates quite low without stopping the growth of other plants. Even so, water lettuce does not like move on the surface. More surface activity causes more small plants.
It needs to cover the water surface for stop the move, or otherwise it will dye outside. Hanging back filters can create problems with it because of that reason.
The plant benefits best in medium to high humidity. The sheets will dry in too low humidity. There are several ways to feed water lettuce, and it can grow well quite a lot with liquid dressings and only LED lighting.
Winter storing water lettuce indoors is quite hard for most folks, even so water hyacinths tend to last more well in such conditions.
Sometimes water lettuce can catch insects. Few black little bugs can appear on the sheets quite sharply. The sheets also can become yellow and brown around the edges after some months.
A purple form of water lettuce exists, but it is very hard to get. Liquid glyphosate works on water lettuce above the waterline, but not on plants in the water, because it is a systemic herbicide, that must beabsorbed by the plant.
